Hi,
There's not to much I can say that hasn't already been said just know that there's a lot of people out there who have been down the path you now find yourself on and are only too happy to give you any help, advice etc you may need. I know that I devoured all the info I could find here when I was 'starting out' and it provided so much 'relief' to me. I think your positive attitude will really help but there will be days when you feel 'down' [believe me, been there] so make use of this fantastic site :)
Just take care of yourself, your body will tell you when it needs to rest, and know that there are lots of people out there sending you healing thoughts, me being one of them!
ps: Bye bye Boris!!
